The problem is on Google's side. From AS15879:

Onderwerp: Re: Youtube CDN unreachable over IPv6
It's not just you, I'm seeing the same thing from my home connection=20
in AS3265. I think this started happening not long ago when Google=20
had an issue with one of their AMS-IX connections.
% telnet -6 r7---sn-5hne6n7y.googlevideo.com 443
Trying 2a00:1450:401c:8::c...
I'm certain it's not AS3265 who is to blame here, an ISP I've had=20
pretty much zero issues with over, IPv6 or otherwise, the many years=20
I've been a customer.
